I don't know about wrist strain, but I find it to be more comfortable. If you don't know how to type properly, I probably wouldn't suggest one, it doesn't help wrist strain or make it easier if you're a hunt and peck typer...
I hate them. I know how to type properly and I am used to certain distances between the keys and when I sometimes sit at a computer with this "ergonomically designed" keyboards, it always takes me forever to find the right keys.
I use one, but I can't type worth ****. rockHEAD is right that it's probably not the best for a 2 or 3 finger guy like me, although I've gotten used to it. My wife is a speed demon on the keyboard, however, and she got one for work. She likes it, but said it takes a little getting used to. She said that you for sure want to have the same thing at home as you do at the office. She hasn't complained about her wrists. She has other things to complain about.
I type properly, and I do an okay job hitting the right keys when trying it out at the store. I suspect I would get better with time as well--then it would be weird using a normal keyboard. Since my work and my home are, well, the same place, I guess it would work for me. I just bought a laptop (which I'm going to use as a "desktop" most of the time) and was thinking of getting a wireless keyboard and mouse, but just can't decide if I want to go the ergonomic route.
It takes a little getting used to but now I prefer it. I'm not sure about the models in the stores, but on ours you can gradually move it away from the normal keyboard at your own pace.
I actually found it comfortable right away and found all keys just fine. I have ergo keyboards at home and at work the only place I don't have one is on my laptop...
I use one of those Microsoft Elite/Natural keyboards and love it. I hate typing on those "normal" flat keyboards at work.
That's what we use. You should bring your own keyboard to work (make 'em buy ya one), if it's feasible. It may not be if you work shifts.
I've got a question about the wireless keyboard and mouse (and I didn't want to start another thread). The Microsoft keyboard and mouse say they'll work within six feet of the "receiver" (or whatever its called). But will it still work even with something between the keyboard/mouse and the receiver? Let me explain what I mean by that: My keyboard and mouse set on a slide out "tray," just like many computer desks have. The wireless receiver, however, will actually sit on the desktop. For all practical purposes, there will be a desktop separating the keyboard/mouse from the receiver. Will that cause any "reception" problems?
